Add root '/' redirect to /app and corresponding test

[mrauter1]

Motivation

• Ensure requests to the site root redirect browsers to the single-page app at /app for a smoother entry point.

Description

• Add a GET handler for / in app/main.py that returns RedirectResponse("/app", status_code=status.HTTP_302_FOUND) and import status and RedirectResponse.
• Add a unit test test_root_route_redirects_to_app in tests/test_auth_requester.py to validate the redirect.

Testing

• Added tests/test_auth_requester.py::test_root_route_redirects_to_app and ran the test suite; the new test passed with the existing tests.

Code Review

This pull request introduces a redirect from the root path to the '/app' endpoint and adds a corresponding test case to verify the behavior. The reviewer suggests using a 301 Moved Permanently status code instead of 302 Found to improve SEO and caching, along with updating the test assertions to match this change.

[gemini-code-assist]

Using 302 Found indicates a temporary redirect. Given that the root is being redirected to the main application entry point, this is likely a permanent change. It's better practice to use a permanent redirect status code like 301 Moved Permanently. This helps with SEO and allows browsers and other clients to cache the redirect.

Suggested change

	return RedirectResponse("/app", status_code=status.HTTP_302_FOUND)
	return RedirectResponse("/app", status_code=status.HTTP_301_MOVED_PERMANENTLY)

[gemini-code-assist]

To align with the suggested change of using a 301 status code for the permanent redirect, this assertion should be updated.

Suggested change

	assert response.status_code == 302
	assert response.status_code == 301
